The first edition of the PostTensioning Manual was published in 1972. Welcome to the leading informational site on the posttensioning construction method, sponsored by the PostTensioning Institute (PTI)a nonprofit organization for the advancement of posttensioned, prestressed concrete design and construction.
PostTensioning Tendon Installation and Grouting Manual Construction via posttensioning (PT) has evolved over the past 60 y as an often preferred approach to affecting integrity for large concrete structures. In the case of bridges, tendon ducts typically contain multiple 15. 24 mm (0. 600 in) diameter, seven wire strands of minimum tensile strength 1, 960 kN (270 ksi), and are invariably grouted.
Add between the 5th and 6th paragraphs of section 501. 01D(3): Perform posttensioning field activities, including grouting, under the direct supervision of a technician After seating, the maximum tensile stress in the prestressing steel must not exceed 75 percent of the Post Tension Tendon Installation and Grouting Manual 2013 Ebook download as PDF File (.

However, instances of corrosioninduced fracture of wires and strands and failure of tendons have occurred as a consequence of either chemically or physically deficient grout (or a combination of these), where the former dot. state. mn. us East 6th Avenue Vehicle Bridge is a cable stayed posttensioned concrete structure crossing a busy Posttensioning (PT) makes possible the costeffective construction of highquality segmental This presentation will introduce the new PT Box Girder Bridge Design Manual developed for the FHWA.
PTI Committee DC40, Bridges, is In response to findings of chloride contaminated grout in a posttensioned (PT) concrete bridge in Texas and similar problems with several bridges in Florida, FHWA initiated a multiphased program to address concerns about potential corrosion.
To this end, a posttensioned splice that eliminates the limitations on tension stresses during driving was developed. This is the first of three papers that detail the development of this alternative approach.
